[Lustre-discuss] Lustre newbie

Without actual error messages and the version of the installed code, I don't think anyone is going to be able to help much.
Personally, the first place I would start is the logs on the MDS. You can also get the lustre version from that node by running:
rpm -qa | grep lustre
Recently, I also inherited a Lustre system (running 1.8.3) which was exhibiting similar issues and upgrading all the lustre servers to 1.8.8-wc1 (and CentOS 5.8) seems to have resolved all the issues.
